403 - Forbidden on trying to build inheritance project

Hi, I have been facing an issue for a while now while trying to fix my user-role structure in Jenkins. My main intention is for a specific role to be able to build only a folder inside Jenkins, and not the others.

To do so, I have tried to create a role, assign it to a specific person or group and, through RegEx, only allowing that role to apply to that folder. However, whenever a user is assigned that role, they are presented with a 403-Forbidden Error if and only if they are trying to build an inheritance project. Freestyles projects work like a charm, which makes me suspect this is somehow a bug in the plugins.

Administrators are able to build that, but setting everyone as admin is not an option. This same logic was working a few months ago, but it seems as though a plugin or Jenkins update might have broken it.

Does anyone have any idea on how to try and fix this? Thanks in advance!!
